Hey all, I have a question about the rear axle and nut that I couldn't seem to find an answer to in the site search. I noticed last night when putting the rim back on that the rear nut now tightens past the cotter pin holes. When I first bought the bike, the holes were near the top of the castle nut to begin with.
It is an 03 busa that I purchased in the fall of 08 and everything in the rear axle assembly is OEM except for the Gilles Chain Adjusters, so I'm not sure if they are thinner than the OEM adjusters which might be affecting this. When I bought the bike, the chain and OEM sprockets were newly replaced and I have since put on about 13,000 kms (7,000 miles) and have adjusted the chain when needed. On the Gilles adjusters, I have moved from approx the 2 mark to the 4 mark since I bought it.
I know that the threads and/or the axle can stretch due to over tightening, but is there any harm in having the nut where it is? The cotter pin is just resting on the top of the castle nut, so it still shouldn't move. I do recall that on my old Katana that I drove for years, that as I neared the end of the adjusters that the same thing would happen with the castle nut and cotter pin. When I replaced the chain and sprockets, thereby moving to the front of the adjusters again, the problem would go away until I neared the end of the adjusters again.
And no, I have never used a torque wrench on the rear axle nut. Because of this, I do not go super crazy in tightening it. I have never needed anything leverage-wise to get the rear nut off other than a socket wrench and 36mm socket. Any thoughts or opinions on this? Obviously, I don't want this thing to move. I know the busa has a lot of hp so I will replace the axle and nut if need be.
Here are 2 pics from different angles.
